Many well-known and efficient technologies for satellite-based localization in open space there exist; however, their accuracy and availability depend on several factors, such as the characteristics of the devices used, the surrounding environment, and the distance from reference stations. In the ALARP (A railway automatic track warning system based on distributed personal mobile terminals) system, it is required to accurately localize workers in railway worksites using low-cost GPS devices. In this paper we present an experimental campaign aimed to quantify the systematic and random contribution to localization errors of cheap GPS devices in railway worksite-like scenarios. The evaluation is performed comparing data from lowcost GPS devices to data collected using a highly accurate reference system. Results provide information to understand the feasibility of GPS-based solutions for the ALARP requirements on localization, and constitute a basis for the definition of a further, more extensive testing campaign.

“…In a word, the goal is to give an answer, based on experimental evidence, to the following question: ''To what extent can low-cost GPS devices be successfully used in the specific ALARP scenario?' ' Although the sources of localization errors for GPS are well-known [12] and have already been widely analyzed in different contexts [11], the specificity and unique requirements of ALARP make a detailed investigation of localization errors in this context relevant [14].…”

Differential global positioning system (DGPS) is important for all kinds of navigation applications which can improve the positioning accuracy from around 15 m provided by standard point service (SPS) to about 1-2 m. It uses a network of continuous operating reference station (CORS) with known positions and broadcasts the correction between the measured satellite pseudoranges and actual (internally computed) pseudoranges, and receiver stations may correct their pseudoranges by the same amount. Hence, in order to implement DGPS, the raw pseudorange measurements of the receiver are required. It is not a problem for general GPS receivers, but for mobile devices with an integrated GPS chip, it is not feasible as the raw pseudorange measurements cannot be accessed for most mobile devices. In order to realize DGPS on mobile, a mobile DGPS (M-DGPS) algorithm is proposed which does not require the raw pseudorange measurements. As the mobile can provide a SPS solution and the satellite names which is used to get the solution, with the correction of these satellites received from the CORS network, a position correction can be calculated. Then, the solution can be improved after applying the position correction. The algorithm is tested in different areas of Fuzhou city, China, and the results show that the new M-DGPS algorithm can improve the positioning accuracy obviously and meet the accuracy requirements of some navigation and surveying applications most of the time in urban environments.
